“…Even though it is not possible to draw a detailed parallel with other systems in the literature, due to the lack of homogeneity in data sets, domains, computing measures and used resources, a few conclusions can be drawn from a qualitative comparison with related approaches: 1. The systems described in [8][9][10][11] do not perform any syntactic analysis. The precision obtained in [9] is similar to ours, but in [8], precision and recall are lower.…”

“…Pattern-based methods can be further divided into two subgroups: those in which extraction rules arise from an initial set of tagged entities [3][4][5], and those in which extraction rules are manually defined [6,7]. Probabilistic machine learning methods rely on statistical models to predict the location of entities in texts [8][9][10][11], while inductive machine learning methods produce entity recognition rules from the syntactical analysis of texts [12][13][14][15][16].…”

“…The Semtag and Seeker system [10] uses the domain ontologies extracted from automatic wrappers [16] to annotate Web pages. Such systems extract relationships and facts that match these patterns from the natural language text segments of the Web pages.…”

“…Our system works without the requirements that (a) the Web pages need to share a similar presentation template or (b) that they need to share the same set of metadata among each other. Hence, we cannot readily use previously developed wrapper induction techniques [4,16,18] which require that the item pages should be template driven or the ontology driven extraction techniques [8,10,11] which require that an ontology of concepts, relationships and their value types is provided apriori in order to find matching information.…”
