Open Source Java Search Engines

Project moved to GitHub! https://github.com/carrot2/carrot2 Carrot2 is an Open Source Search Results Clustering Engine. It can automatically organize small collections of documents, e.g. search results, into thematic categories. Carrot2 integrates very well with both Open Source and proprietary search engines.

This package contains different tools to add NLP capabilities for Lucene 4.x (it has been tested using Lucene version from 4.6.x to 4.8.1). Although it was originally developed for German, it is, mostly, language independent. It allows the user to lemmatize words to be indexed, to weight termy ba their parts of speech (e.g. weighting nouns mor hevaily than pronouns), and to add synonyms taken from GermaNet or a list you provide to the search index and thereby increase recall of lucene.

A library to support spread activation techniques over ontologies.

The implementation of Bee Hive @ Work algorithm that simulates the foraging behavior of honey bees in nature. The aim is to provide an extensible framework that can be used by researchers to simply create new applications of this algorithm.

This project tries to find geographical locations (formulated by GPS positions) for specific queries (eg 'art') in specific environments (eg 'Maastricht') by analyzing webpages.

HORUS is a system for knowledge acquisition, hypothesis generation, inference and learning. It is an interactive, internet environment accessible to a diverse community of users (public-access or membership basis) - see also UMKAILASH project for more.

IDEAL means Information DEALer. A System wich provides the news and articles which the user wants. Using Tomcat, Struts, Java, MySQL an AgentSystem, Clustering, TF/IDF, Document Parser and it is multi user able.

IGLU is a Java class library designed to facilitate sharing of code among Artificial Intelligence/Information Retrieval researchers to illustrate how various problems can be solved in Java. It is developed and maintained by the IGLU Research Group.

Web-as-corpus tools in Java. * Simple Crawler (and also integration with Nutch and Heritrix) * HTML cleaner to remove boiler plate code * Language recognition * Corpus builder

JobHunter aims to automatically find job information from some big sites such as chinahr,51job,zhaopin and so on. JobHunter searches the email address of each job item and automatically sends a email of application text to it.

The Jorne project develops software and open standards for linking Lojban text with WWW and Semantic Web metadata (e.g. RDF/N3, RSS, XML). Lojban is an artificial spoken and written language based on predicate logic.

A web-based, automated search engine that responds to user feedback through the use of artificial intelligence.

META Spider is a neural network powered search engine which aim is to determine if a given raw information is relevant, using the experience of the active user of the hosting computer as a reference.

This project aims to build a suite of Natural Language Processing tools. Modules will include corpus indexing and access tools, a part-of-speech tagger, tokenisers, text classification software, etc.

This project intends to create an indexing search engine, for knowledge management. The primary object is to apply an information retrieval core. And implement a knowledge data discovery theory such as data mining algorithm, text mining.

NeuroGrid could be thought of as a "Napster for Bookmarks." It allows the user to store data in a web-like fashion, allowing you to associate bookmarks (files/documents/whatever) with multiple keywords. See http://www.neurogrid.net

A DAML+OIL ontology editor with constraint propagation functionality to ensure that constraints applied to properties and restrictions are correctly propagated through an ontology, and datatype management functionality for manipulating custom datatypes.

The OpenBorges project intends to provide an humble place to experiment, and debate, about what can be an open, distributed, adaptive and collaborative, semantic virtual library. Inspirations are: As we May Think, Library of Babel, and Weaving the web

A Distributed Web Search System bassed on current high level nerual network ai for the rating algorithum and search direction.

SSWAP (Simple Semantic Web Architecture and Protocol; pronounced "swap") is an architecture, protocol, and platform that uses reasoning to semantically integrate disparate data and services on the web. Running live at http://sswap.info.

SYRAH si propone di far emergere e rappresentare i concetti espressi per mezzo di un linguaggio naturale. SYRAH aims to discover and represent concepts expressed in natural languages. NLP, lemma, lemmario, italiano, rete, semantica, clustering, semantic

Scidoc N6 is a platform for collaborative research and learning based on Semantic Web standards like RDF and OWL. It supports dynamically evolving conecpt models as a foundation for various kinds of information systems.

Please click on "BROWSE ALL FILES" to open a README! What is this program? This program is meant to search the texts and suggest sentences that might follow any inputted sentence. It was meant to help composing the writings. How was it made? First, I made a chatterbot to understand the concept of "predicting" the next sentence (worked as good as the Cleverbot), then I made this program that is aided by an user to compose the new writings. SAMPLE: Input sentence was "Learning algorithm" The prefix was "transductive learning" Learning algorithm. Transduction, or transductive inference, tries to predict new outputs on specific and fixed (test) cases from observed, specific (training) cases. The simplest realization for transductive inference is the method of k-nearest neighbors. Learning to learn learns its own inductive bias based on previous experience. ...AND SO ON.... Enjoy the program !

SENTENSA Knowledge Miner is a platform independent tool for searching any text. SENTENSA uses robust methods of indexing and searching text, leveraging on experience from more than 20 years of information retrieval.

TestEl is a Java-based learning analyzer for HTML (and possibly other) structured documents. It can be trained to detect structures in such documents and renders hits in XML.
