IssueCrawler
The IssueCrawler is web network location and visualization software. It consists of crawlers, analysis engines and visualisation modules. It is server-side software that crawls specified sites and captures the outlinks from the specified sites. Sites may be crawled and analyzed in three ways: co-link, snowball and inter-actor. Co-link analysis crawls the seed URLs and retains the pages that receive at least two links from the seeds. Snowball analysis crawls sites and retains pages receiving at least one link from the seeds. Inter-actor analysis crawls the seed URLs and retains inter-linking between the seeds. The Issue Crawler visualises the results in circle, cluster and geographical maps.
