In a previous paper we presented various ideas on how information retrieval on mind maps could enhance applications such as expert systems, search engines and recommender systems. In this paper we present the first research results. In a brief experiment we researched link analysis respectively citation analysis, if applied to mind maps, is suitable to calculate document relatedness. The basic idea is that if two documents A and B are linked by the same mind map, these documents are likely to be related. This information could be used by item-based document recommender systems. In the example, document B could be recommended to those users interested in document A. In addition, we propose that those documents linked in high proximity within a mind map are more closely related than those documents linked in lower proximity. The results of our experiment support our ideas. It seems that link analysis applied to mind maps can be used for determining the relatedness of documents and therefore for improving document recommender systems.

[Show abstract][Hide abstract]ABSTRACT: Web search, academic search and expert search engines often have difficulties in classifying and ranking objects and generating summaries for them. In this paper I propose that data retrieved from mind maps may enhance these search applications. For instance, similar to anchor text analysis, documents, i.e. web pages or academic articles, linked in a mind map might be classified with text from the linking nodes. This idea, along with additional ideas, related work, the indented methodology, and first research results are summarized in this paper.
[Show abstract][Hide abstract]ABSTRACT: In this paper we present how sharing and utilizing mind maps could enhance search applications such as document search engines and recommender systems. In addition, we briefly present the first research results which indicate that mind maps can be used to determine document relatedness and therefore can enhance document recommender systems. We also discuss some challenges that information retrieval on mind maps will probably have to overcome.
