Emergent System for Information Retrieval1

چکیده
Stand alone as well as distributed web crawlers employ high performance, sophisticated algorithms which, on the other hand, require a high degree of computational power. They also use complex interprocess communication techniques (multithreading, shared memory, etc). As opposed to the distributed web crawlers, the ERRIE crawler system presented in this paper displays emergent behavior by employing extremely simple algorithms that are very efficient when dealing with a large number of entities but are unpredictable and nondeterministic. The paper discusses the ERRIE web crawler system alongside with a comparison between it and a common, standalone web crawling application called WIRE.

INTERNET Challenges for Information Retrieval1
This paper examines the problem of Internet resource discovery from the point of view of Information retrieval. It firstly discusses the traditional Information Retrieval task, and then considers current approaches to Internet Information Retrieval. These approaches give rise to problems such as Information Burial, which are defined and discussed. Finally, a model is proposed that partially cir...

متن کاملDistance Map Retrieval1
The paper describes a new method for indexing and retrieval of photographic images: we propose to involve the distance information of objects for indexing. We applied the “range-from focus” technique for distance estimation combined by statistical segmentation. This technique doesn’t require stereo and it is easy to be implemented in conventional digital cameras. Test results illustrate relativ...
متن کاملInland wetlands mapping and vulnerability assessment using an integrated geographic information system and remote sensing techniques
The understanding of inland wetlands’ distribution and their level of vulnerability is important to enhance management and conservation efforts. The aim of the study was to map inland wetlands and assess their distribution pattern and vulnerability to natural and human disturbances such as climate change (temperature increase) and human activities by the year 2080. Inland wetland types i.e. for...
