Information from computer programs can be extracted from its source code, external documentation, and compiled code. Although compiled code is an assured information source which is always exists in published computer programs, it is seldom used by the existing search engines since some reverse engineering tasks are needed. In this research, a search engine for Java archives that uses byte code (compiled...
Bio-inspired computing is the idea to emulate and to get inspirations from biological systems which is then used to solve complex problems. Artificial immune systems, as one of the bio-inspired computing has contributed in solving complex problems. From one generation to another generation, AIS's practitioners realize that to get better algorithms we need the inspiration with the better understanding...
This paper proposes a method to improve the performance of information retrieval systems by expanding queries using heterogeneous thesauri. The expansion terms are taken from a hand-crafted thesaurus, co-occurrence-based automatically constructed thesaurus, and predicate-argument-based automatically constructed thesaurus. To avoid the effects of wrong expansion terms, a weighting method is devised...
