Hi all, Gephi organization (http://gephi.org), open-source graph visualization plaform is looking for students application about integrating Lucene to Gephi.
If you look around you, you may notice that networks are everywhere. For instance, social networks, relationships among people or computer networks, links between computers. Transportations routes, power grids, emails networks or the relations between scientific papers are other examples of networks. The ability to analyze, manipulate and represent a network is a key-feature for solving difficult problems and boost knowledge discovery in many disciplines. You may already know how Google SoC works, basically a student will receive payment ($5,000) for working on a mentoring open-source projects. Short version of the Lucene Proposal: Networks are generally associated with data. Considering a social network, people have attributes like age, gender, country and more subtle info. In Gephi, attributes are all the data related to nodes and edges and are organized in a row-column system. Columns could be any type like String or Double and rows are elements (nodes or edges). The current system is entirely loaded into memory and obviously becomes very large when manipulating large graphs with many attributes. The aim is to use Lucene to store attributes on the disk and index them in order to be searchable. The system should have a well-designed cache system to handle heavy read access on some elements. Though the need is not as critical as the graph structure, several features in Gephi need in-memory attributes to work properly. Gephi will sponsor the purchrase of a Lucene book if necessary.
