Many systems have been developed in the past few years to assist researchers in the discovery of knowledge published as English text, for example in the PubMed database. At the same time, higher level collective knowledge is often published using a graphical notation representing all the entities in a pathway and their interactions. We believe that these pathway visualizations could serve as an effective user interface for knowledge discovery if they can be linked to the text in publications. Since the graphical elements in a Pathway are of a very different nature to their corresponding descriptions in English text, we have developed PathText to serve as a bridge between these two systems.
The PathText Project has the following goals:
- to adapt and develop text mining tools to evaluate the basis in the literature for the structure of biochemical and signalling models in systems biology
- to integrate text mining techniques with visualisation technologies for better understanding of the evidence for biochemical and signalling pathways
- to enrich models encoded in the Systems Biology Markup Language (SBML) with information derived from text mining
- to evaluate in conjunction with domain experts the effectiveness of using models of pathways augmented with evidence derived from text mining
The current PathText prototype uses the Payao Web 2.0 community tagging system for biological networks (see acknowledgements b,c,d below) as a web based user interface to let the user quickly find related text snippets and articles related to the different parts of the Pathway.
The text mining is carried out by the MEDIE, Facta and KLEIO systems, which rely on many databases and other enabling technologies like the Systems Biology Markup Language (SBML), Systems Biology Graphical Notation (SBGN) (see acknowledgement a below) and the CellDesigner program which is used to show graphical models.
