Automatic Indexer for Polish Agricultural Texts

Today, the majority of resources are available in digital forms to acquire information. We have to search through collections of documents. In this paper text indexing which can improve searching is described. Next, indexing tool, the Agrotagger, which is useful for documents in the field of agriculture, is presented. Two available versions of the Agrotagger are tested and discussed. The Agrotagger is useful only for the English language despite the fact that it uses multilingual thesaurus Agrovoc. Because of the Agrotagger is not useful for texts in Polish, it is important to create similar tool appropriate for the Polish language. The problems connected with extensive inflection in languages such as Polish language in the process of indexing were discussed. In the final part of the paper, it is presented design and implementation of a system, based on the Polish language dictionary and the Agrovoc. Additionally some tests of implemented system are discussed.
