This paper reviews several evaluation measures developed for evaluating XML information retrieval (IR) systems. We argue that these measures, some of which are currently in use by the INitiative for the Evaluation of XML Retrieval (INEX), are complicated, hard to understand, and hard to explain to users of XML IR systems. To show the value of keeping things simple, we report alternative evaluat...

Information Retrieval (IR) is used to store and represent the knowledge and the retrieval of information relevant for a special user query. Multilingual Information Retrieval (MLIR) system helps the users to pose the query in one language and retrieve the documents in more than one language. One of the basic performance measures of IR systems is Precision. While this measure work well in monoli...

Large amount of unstructured designed information is difficult to deal with. Obtaining specific information is a hard mission and takes a lot of time. Information Retrieval System (IR) is a way to solve this kind of problem. IR is a good mechanism but does not give the perfect solution. Other techniques have been added to IR to develop the result. One of the techniques is text classification. T...

In this contribution, an information retrieval system (IRS) based on fuzzy multi-granular linguistic information is proposed. The user queries and IRS responses are modelled using different linguistic domains or label sets with different cardinalities and/or semantics. We present a method to process the multigranular linguistic information in the retrieval activity of the IRS. The system accept...

The primary objective of document annotation in whatever form, manual or electronic is to allow those who may not have control to original document to provide personal view on information source. Beyond providing personal assessment to original information sources, we are looking at a situation where annotation made can be used as additional source of information for document tracking and recom...

Many Information Retrieval courses take a reductionist approach: reducing the complexity of Information Retrieval systems into a series of decomposed modules for indexing, retrieval, and results presentation. In this short paper we describe a complementary approach for practical coursework that encourages students to take a holistic approach to thinking about Information Retrieval systems. This...
