Hyperlink-Induced Topic Search (HITS; also known as hubs and authorities) is a link analysis algorithm that rates Web pages. See more here: https://en.wikipedia.org/wiki/HITS_algorithm Args: graph (:class:`Graph`): A projected simple graph. tolerance (float, optional): Defaults to 0.01. max_round (int, optional): Defaults to 100. normalized (bool, optional): Whether to normalize the result to 0-1. Defaults to True. Returns: :class:`graphscope.framework.context.VertexPropertyContextDAGNode`: A context with each vertex assigned with the HITS value, evaluated in eager mode. Examples: .. code:: python import graphscope as gs sess = gs.session() g = sess.g() pg = g.project(vertices={"vlabel": []}, edges={"elabel": []}) r = gs.hits(pg) s.close() """ tolerance = float(tolerance) max_round = int(max_round) normalized = bool(normalized) return AppAssets(algo="hits", context="vertex_property")( graph, tolerance, max_round, normalized )
