Guide Structures in CD-ROM Dictionaries , with Specific Reference to the EWED and the ELHAT

Much of the success of modern dictionaries depends on the accessibility of their macroand microstructural information. In order to evaluate the methods which lexicographers employ to improve dictionary accessibility, the concept of guide structures was introduced by Hausmann and Wiegand (1989). Since the appearance of that article, various academics have written articles and read papers on guide structures in print dictionaries, but few studies have focussed on the tremendous potential of guide structures in electronic dictionaries. In this article it will be shown that electronic dictionaries add dimensions to the implementation of guide structures not possible in print versions. The role of two of the guide structures in the transfer of information in CD-ROM dictionaries will be discussed. The access and mediostructures of the Microsoft Encarta World English Dictionary and the Elektroniese Handwoordeboek van die Afrikaanse Taal will be analysed and critically evaluated to illustrate the advantages of electronic dictionaries over print dictionaries and the urgent need for metalexicographical discussion of this publication medium.

Two of the roles of the guide structures in the transfer of information in CD-ROM dictionaries will be discussed.The access and mediostructures of the Microsoft Encarta World English Dictionary (henceforth EWED) and the Elektroniese Handwoordeboek van die Afriknanse Taal (henceforth ELHAT) will be analysed and critically evaluated to illustrate the advantages electronic dictionaries hold over print dictionaries and the urgent need fol' meta lexicographical discussion of this publication medium.

Access structures in electronic dictionaries Louw (1999: 109) describes the access structure as "the primary guide structure".It is through the use of the access structure, of any dictionary that the necessary information is found.The macro-and microstructural content of a dictionary may be adequate or even excellent, but without an adequate access structure the user may very well be frustrated in his/her search.Gouws and Prinsloo (1998: 18) affirm this point: "One of the most important characteristics of a good dictionary is its accesSibility.AcceSSibility leads to an unambiguous retrieval of the information presented on both the macro-and microstructural levels." Guide structures in CD-ROM dictionaries
2.1 The outer access structure

The outer search path
In electronic dictionaries, as in print dictionaries, the user follows an outer search path which takes him/her to the desired article and is aided on this search path by the outer access structure.The outer access structure can be divided into a rapid outer access structure and a standard outer access structure.

The rapid and standard outer access structures
In print dictionaries, the rapid outer access structure usually consists of elements such as indexes, thumb indexes, running heads and any features which bring the user rapidly to the vicinity of the article in which the relevant information is presented.Louw (1999: 111), however, states: "It cannot guide the user along the last, most vital part of the outer search path.The final choice of the desired macrostructural element is made by means of the standard outer access structure."Most print dictionaries are monoaccessible, i.e. the standard outer access structure corresponds to the macrostructure.This standard outer access structure encompasses decisions made by the lexicographer on, for example, an initial alphabetical or a thematic listing of lemmata, as well as the consistent implementation of these decisions.
In electronic dictionaries, it is not always easy to recognise the boundaries between the rapid and standard outer access structure.In the ELHA T there is a traditional presentation similar to that of the print version of this dictionary, but also some innovative hybrid elements.In the EWED innovative methods are employed throughout, combining elements of the rapid and standard outer access structures into single items or texts.

ELHAT
At first glance, the ELHAT seems to provide a conventional outer search path.The opening 'browse" screen provides several elements of the rapid outer access structure (see Fig. 1).
Phillip Louw ---Fig. 1 An outline is given in a window on the left side of the screen.This outline provides active cross-references to transport the user to texts of the print version's front matter, the central text or an additional help text or user's guide which deals specifically with the structure, search patterns, etc. of the electronic version.The outline can provide rapid access to the macrostructure and therefore forms part of the rapid outer access structure.It shares this function with a button marked "Sentrale Teks" in the main window.A click here or in the outline will take the user to the central text, which is presented in scroll able format in the main window (the central text can be accessed separately by clicking on the icon entitled "Document" at the bottom of the screen).
At this point other elements of the rapid outer access structure take over.As a first step, the user can click on any of the 26 buttons representing the letters of the alphabet and will then be transported to the first lemma starting with that particular letter.From there the user can follow the standard outer search path by scrolling down to the lemma he/she is looking for.In order to maintain the "user addressing" (Louw and Gouws 1996: 98) of the print version, which is aimed at a very broad spectrum of Afrikaans speakers, the initial standard alphabetical outer access structure of the print version is retained unchanged.The elements of the rapid outer access structure which usually guide the user when turning the pages -the running heads -are, however, replaced.In the top right a small window shows which letter is currently consulted and displays the lemma sign of the article where the cursor is situated.This assists the user when he/she is scrolling rapidly through the central text.
---Th~s far, all the elements have been fairly conventional and aimed at f~ ring the user a look-up experience very similar to what he/she would o e rience when consulting the print version.The ELHAT does provide altere"~:e search patterns, though.The initial alphabetical standard outer access na cture can also be searched by using the customised "Soekwoorde"-window (see Fig. 2), which can e ca e up om e searc -menu.
Fig. 2 A search using this tool bypasses conventional methods of searching and collapses the rapid and standard outer access structures into one by providing rapid access not only to the macrostructure, but also to the desired article.
A further innovation is the "Soekvelde"-window which presents an alternative to the conventional initial alphabetical standard outer access structure.A few simple procedures divide the macrostructure into thematic groups of lemmas (see Fig. 3).Fig. 3 By selecting a field and then clicking in the "Tik woord in"-input box, a hit list appears in the "Groep en Woordelys"-display window (see Fig. 4).

Fig. 4
Each group of lemmas represents a hit list, which can be searched by scrolling through them or by refining the search by typing in a search word.A click on "OK" will then take the user to the correct article.

EWED
The EWED-CD-ROM includes a thesaurus, a dictionary of quotations, a general monolingual dictionary and two bidirectional bilingual dictionaries.By choosing "everything" on the opening screen, searches can be conducted throughout all these dictionaries.For the purposes of this article, however, the procedures following the choice of "dictionary" on the opening screen will be focussed on.This link takes the user to the outer access structures of a general monolingual dictionary.
The outer access structure differs significantly from that of ELHAT.On the main window of both dictionaries, links are provided to various parts of the front matter, but whereas ELHAT has a link to the central text and search boxes available from menu items, EWED has a search aid that is always on the left side of the screen.This "pinpointer" is a trademark feature of the Encarta family.In the previous version of the Encarta Encyclopedia it acted as a "floating help text" (Louw 1999a: 288), but in both the Encarta Encyclopedia 2000 and EWED it is in a fixed position, which makes it easier for the target user to access.
As was the case with the search boxes in ELl1AT, elements of the rapid and standard outer access structures are combined very effectively in EWED.The "pinpointer" lists the macrostructural items strictly alphabetically and scrolling down to the relevant lemma and clicking on it can access these (see Fig. \5).The main window then displays the selected article.In this procedure the "pinpointer" forms part of the standard outer access structure and has an important function.In cases where someone is unsure of the spelling of a lemma, it affords him/her the opportunity to find the desired lemma in a search procedure that he/she would be familiar with in a print dictionary.This appreciation of familiarity is an important part of the user-friendliness of EWED.Louw's (1999a: 289) evaluation of the "pinpointer's" role in the Encarta Encyclopedia is therefore also valid here: "It is the preference for an initial alphabetic listing as the first step in searches using the 'pinpointer', that proves this commitment to the needs of target users, as an alphabetical listing would probably be preferred by families within the current dictionary culture".
Yet the "pinpointer" also functions as an element of the rapid outer access structure.Once the radio button labelled "Articles about" is activated a search word or phrase can be entered into the "Find" input box.The macrostructure of the dictionary is immediately scanned and the results are narrowed down as each letter is typed in.The relevant lemma is highlighted in the main display box of the "pinpointer".From here the article can be accessed directly and swiftly by a click, or the user can choose to follow a different, integrated search path.';'-";~ Fig. 6 00 --This search function is especially useful if the user needs more detailed ti 'on about a search term than is contained in the article with that term '_'or1l'\a a if the user needs to know I a term not emmatise as part q the itS lernrn~cture exists, or if the user is eager to learn about the semantic rela-~a:~etween the search term and other lexical items.The procedure is, how-DO not always applied consistently enough to be of full value to the user.If ever, arches for "laser", for example, the first lemma on the list is lase.
one s~ this article all derivatives of lase are highlighted in. the microstructure, whereas the user searche~ for "laser" (see Fig. 6).Th~ user must.ther~for~wade through useless information.to reach the requested Item.The sltuatiO~ IS e~e~ J desirable in the next article, that for Las Palmas.The search term.laser IS e~ even present, with "Las" being highlighted.This degree of inaccuracy in :rches frustrates the user and should be addressed in future editions of the EWED.

ELHAT
The ELHAT is far more advanced in this type of procedure.It provides two valuable query options.The first is a basic query that is similar to that of the EWED.A query-form can be selected from the search menu option and a search term entered (see Fig. 7).

Fig. 7
The results will be compiled in a hit list, which can be accessed by clicking on the "HitList"-icon at the bottom of the main window.See for example the hit list for karkas (Fig. 8).
The hits can be selected individually and viewed in the document section by double-clicking on the selected item. .There is also a more advanced query procedure that illustrates the atten-~on to the needs of the target userS of the dictionary.The compilers of the dictionary knew that the target users frequently employ the dictionary as an aid in crossword puzzles.Rather than dismissing this need as unacademic, they have chos:;n to accommodate the users by making a "wild card"-search available.!he Advanced Query"-form can be accessed from the "Search"-menu item and 15 easy to use (see Fig. 9).

Phillip Louw ----
The question mark was chosen as a structural marker in the search term t denote which letters of the term are not known.It is a good choice, as mos~ users are familiar with this marker and what it denotes.The entry of a search term will lead to a selection of articles in the "Word"-list box and a COrre_ sponding selection in the hit list which can be accessed in the same way as that of the normal query.

2.3
The inner access structure

The inner search path
Most of the innovations in the CD-ROM dictionaries guide the user on the outer search path.As was shown in 2.2, however, there are some innovative search procedures that stretch to the inner search path.There are also some elements of the inner access structure which are unique to electronic dictionaries.
These unique elements will be discussed in this section.Elements of the inner access structure which are truly innovative in EWED, but are also included in the print version of this dictionary, will therefore not be discussed.

EWED
In the EWED, on the other hand, the use of multimedia has necessitated a fresh approach to the inner access structure.The first and most important multimedia element in EWED is the aid in pronunciation.There is an icon denoting a speaker next to some lemmas, which, if clicked on, provides the pronunciation in the form of a sound clip.The user is therefore granted rapid access to an accurate pronunciation.The icon denoting the speaker acts as a structural marker that forms part of the rapid inner access structure.
The EWED can be classified as an encyclopaedic dictionary that breaks with the traditional distinction between encyclopaedia and linguistic dictionary, opting for a hybrid format.On a macrostructural level this has, for example, led to the inclusion of place names, etc.On a microstructural level it has not only had implications for the level of encyclopaedic information contained in the items giving the meaning paraphrases, but also owing to the inclusion of multimedia items that supports the transfer of encyclopaedic information.These include maps, diagrams, pictures (mostly photographs) and sound clips (such as the anthems of countries whose names have been lemmatised).The visual items are usually included as inserted inner texts, but in many cases these small items act as active cross-references which provide rapid access to enlarged versions of the inserted inner texts.The sound clips are introduced by means of an abstract icon.In all these cases the items act not only as cross-references, but also as effective, unique structural markers of the inner access structure, which introduce the multimedia.

3.
The mediostructure CD-ROM dictionaries have not only broken new ground with the inner and outer access structures.Some of the most telling innovations are to be found in their mediostructure, which encompasses all lexicographic cross-references in a dictionary.

EWED
As was shown in 2.3.2,active cross-references have a significant role in the successful use of multimedia, where smaller versions and abstract icons are used as links to separate audio and visual elements.In the case of visual elements such as maps or pictures, these links invariably lead to an illustration, which operates as a text that does not form part of ~e central text.The cross-references in this case are therefore text-external cross-references.
Active text-external cross-references are employed to great effect elsewhere in EWED.The active link to audio clips giving the pronunciation was discussed in 2.3.2, but these are not the only innovations in the pronunciation information.Whereas only some lemmas have audio clips, transcriptions are provided for almost all lemmas.These transcriptions have a green font colour, which shows that they are active text-external cross-references.A click on the pronunciation takes the user to a pronunciation guide, which can also be accessed separately as part of the front matter (see Fig. to).
These cross-references offer instant help to the user who struggles with the pronunciap,on of a specific lemma.They improve the user-friendliness of EWED considerably and should be adopted by other CD-ROM dictionaries.Note: This dictionary uses double letters to show many sounds in the middle of words, because English spelling normall y uses dou ble I etters in these positions.This is one of several ways that the system of .spellingpronunciations here is more natural and easier to use than the systems in many other dictionaries.
Fig. 10 EWED's more conventional text-internal cross-references are also active.The explicit remote article-external cross-references are given in blue text and have an important role to play in maintaining the textual cohesion of this dictionary.A click on the explicit reference "See also genie" in the article of jinni will take the user directly to genie, where the cross-reference is met by a corresponding active cross-reference to complete the circle.This is unfortunately not always the case.The explicit cr,ass-references to abalone at ear shell and sea ear are active, but their corresponding cross-references at abalone are not.Explicit article-external cross-references that are complicated by polysemy are not treated adequately.In the case of the synonymous pair hemp and marijuana, for example, the use of cross-references is confusing.A cross-reference "See also marijuana" is listed under the correct sense of hemp, but it is not specified whether hemp can be used as a synonym for both senses of marijuana or, if not, for which sense it can act as a synonym.Once again the circle is not completed by a corresponding active cross-reference at the address of this cross-reference (i.e.marijuana).This creates even more confusion in the user's mind and compounds the error made by the compilers.
Deliberately monodirectional explicit article-external cross-references are also employed in EWED, with more success.They are particularly effective when used in the etymology article position.In the case of genie, for example, the etymology is related to the Latin "genius".Instead of repeating the full etymology of "genius", the user can .clickon the cross-reference "(see genius)" and be transported to the article for genius in which the full etymology is explained.
Not all the article-external cross-references are explicit though.Probably the most innovative mediostructural elements are the implicit cross-references.A double-click on any word in the microstructure, will prompt a small screen called "Quickdefine" to appear.One can, for example, highlight "panama hats" in the the microstructure of jipijapa and double click with the result as shown in Fig. 11.This is yet another user-friendly feature of EWED that gives the user rapid access to the information he/she desires.EWED goes one step further by allOWing users to obtain a "quickdefine"-window for search terms in ordinary Windows-based word processors such as Microsoft Word by highlighting the term and then clicking on the quickdefine desktop item, ra ther than opening the whole dictionary.The emphasis in both these procedures is on fast, effective access to the desired information.

ELHAT
ELHA T's mediostrucrure has unfortunately not even remotely reached the standards of innovation set by EWED, as is to be expected in such a far more modest attempt.The mediostructure is restricted to explicit article-external cross-references.These are generally well implemented and in the case of cross-
