6.5 Technical challenges Figure 6.14: UniArab’s lexicon interface 6.5. TECHNICAL CHALLENGES Arabic letters in the GUI We can not write Arabic letters in UniArab’s GUI. We use Unicode to represent them. Unicode Converter System allows us to enter Arabic text and click on a button to get the equivalent Unicode of the text. Arabic letters in Eclipse IDE for Java We used Eclipse IDE for Java development. We can not write Arabic as a string in Eclipse. While Java does support Arabic, the problem lies in the operating system not supporting Arabic letter shapes in IDE. We used Windows XP and Windows 2000 which both have the same problem. To fix this we changed to Ubuntu Linux. Under Linux we can write Arabic text as a string in the Eclipse IDE. Arabic in data source We choose to create our data source as XML, for optimum support or different platforms. It was also easier as we used Arabic letters not Unicode inside the data source. XML fully supports Arabic. We created our search engine using Java. We used a HashMap to make the keyword in Arabic when we search inside the datasource. We used verbMap.containsKey(word) in order to check the presence of an Arabic word in the data source. 98
6.6 Summary 6.6. SUMMARY We presented the conceptual structure and architecture of the UniArab system. We discussed each of the phases from source language analysis, through the logical representation, then the generation of the target sentences. We detailed the lexical properties of Arabic sentences and the attributes for each type of word. We discussed how generation maps the logic structure to the target language. Finally, we discussed the user interface and some of the problems encountered during development. 99
