Text Subject, Semantic Analysis, IndexingAbstract
This article presents a specific issue of the semantic analysis of texts in natural language – text indexing and describes one field of its application (web browsing).The main part of this article describes the computer system assigning a set of semantic indexes (similar to keywords) to a particular text. The indexing algorithm employs a semantic dictionary to find specific words in a text, that represent a text content. Furthermore it compares two given sets of semantic indexes to determine texts’ similarity (assigning numerical value). The article describes the semantic dictionary – a tool essential
to accomplish this task and its usefulness, main concepts of the algorithm and test results.
