## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to search results characterization in a search engine and more particularly to search results characterization in a Web log (“blog”) search engine.
2. Description of the Related Art
Content distribution serves a core function of the Internet. From the earliest days of Internet computing, tools such as “Archie” and “Gopher” provided content retrieval mechanisms in which content—namely academic and technical publications—could be located and retrieved, even if the identify of a retrieved publication had not been known a priori. Nearly two decades ago, with the development and commercial deployment of the World Wide Web (the “Web”), content searching tools experienced a dramatic leap forward with the development of several commercially accessible search engines specifically geared to content distributed over the Web. Even today, search engine technology for Web based content continues to evolve in ways unimaginable even just a few years ago.
In the prototypical search engine, in a process often referred to as “spidering”, a computer program periodically (or today, continuously) probes Web accessible content sources—namely Web sites—parses the textually content of the content sources and incorporates the parsed content into an index. Thereafter, query terms can be received through a generic user interface (UI) and the index can be consulted to identify indexed content containing one or more of the query terms, also referred to as search terms. Finally, a result set can be presented in the UI to the querying end user. Optionally, the relevancy of each result set can be provided in the result set indicating a percentage of query terms appearing in the result set. Further, the result set can be sorted according to relevance so that the most relevant results appear at the beginning of the list for ease of access by the querying end user.
While search engine technology has formed part and parcel of the daily Internet experience for the typical end user in respect to content on the Web, the efficacy of the traditional search engine has not translated well to the “Blogosphere”. The term “Blogosphere” refers to the collection of Web logs (“blogs”) accessible through the Web or outside of the Web. As it is well known, a blog is essentially an open diary produced by an author expressing thoughts either amorphously, or more typically in accordance with a theme. Thus, blog postings and indeed the entirety of a blog, often is associated with one author or a collective of authors. Thus, while the content itself of a basic Web page may be the only important aspect of the Web page from the perspective of an end user searching Web content, in the Blogosphere, the content of the blog in addition to the nature of the author of the blog can be equally as important. Yet, the conventional search engine does not account for the nature of the author in performing content searching.
BRIEF SUMMARY OF THE INVENTION
Embodiments of the present invention address deficiencies of the art in respect to content searching blogs and provide a novel and non-obvious method, system and computer program product for authorship accountability in a blog search engine. In an embodiment of the invention, a method for authorship accountability in a blog search engine is provided. The method includes receiving a search engine query specifying both query terms to query blog content and also authorship criteria for authors of blog content in respective entries of a results set returned by the search engine query. The method additionally includes evaluating the authorship criteria for each author of corresponding blog content returned by the search engine query and computing a relevance for each entry in the results set based upon the evaluated authorship criteria. Finally, the method includes presenting in order of relevance a listing of blog content corresponding to the results set.
In one aspect of the embodiment, the method further can include receiving in the search engine query content criteria for the blog content in the respective entries of the results set returned by the search engine query and evaluating the content criteria for blog content returned by the search engine query before computing the relevance for each entry in the results set based both upon the evaluated authorship criteria and also the evaluated content criteria. In another aspect of the embodiment, the method additionally includes weighting with disparate weights the content criteria and the authorship criteria.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.



BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
FIG. 1 is a pictorial illustration of a process for authorship accountability in a blog search engine;
FIG. 2 is a schematic illustration of a blog search engine data processing system configured for authorship accountability in a blog search engine; and,
FIG. 3 is a flow chart illustrating a process for authorship accountability in a blog search engine.



DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the invention provide for authorship accountability in a blog search engine. In accordance with an embodiment, authorship characteristics can be accounted for in performing a search of blog content in the Blogosphere. In this regard, when querying blog content according to one or more query terms, at least one authorship criteria can be specified for the blog content, such as the trustworthiness of authors corresponding to located blog content and a degree to which the authors are deemed an authority with respect to the located blog content. Further, non-authorship, content criteria pertaining to the blog itself can be factored in the search including a number of times a blog has been viewed or the presence or absence of one or more keywords in tags for the blog content. The authorship criteria, and optionally content criteria, can be weighted according to the subjective importance to the end user initiating the search and a result set can be presented according to a relevance of each result computed based upon the authorship criteria and, optionally, the content criteria. In this way, authorship characteristics can be accounted for in searching blog content in the Blogosphere.
In further illustration, FIG. 1 pictorially shows a process for authorship accountability in a blog search engine. As shown in FIG. 1, an end user 110 can direct a query of blog content 140 through a search engine 130 configured to search the blog content 140 according to one or more query terms. In addition to specifying one or more query terms 120 for the query, the end user 110 also can specify authorship criteria 150 to be evaluated against different authors of blog content 140 returned in a result set 180 for the query, and also content criteria 160 to be evaluated against the blog content 140 returned in the result set 180 for the query.
The authorship criteria 150 can include, for example, an indication of the degree to which a blog author of blog content 140 in a result set 180 is deemed knowledgeable, or trustworthy. Likewise, the content criteria 160 can include, for example, an indication of whether or not one or more tags have been applied to the blog content 140 in the result set 180, or an indication of a number of instances the blog content 140 in the result set 180 has been viewed. Of note, authorship sensitive relevance processor 100 can apply the authorship criteria 150 to the result set 180 in order to rearrange the result set 180 into a relevance based result set 190. Optionally, the processor 100 can consider the content criteria 160 to further compute the relevance of each result in the result set 180. To that end, different criteria 150, 160 can be associated with different weights 170A, 170B in order to weight some of the criteria 150, 160 or less than others of the criteria 150, 160.
The process described in connection with FIG. 1, can be implemented in a blog search engine data processing system. In yet further illustration, FIG. 2 schematically shows a blog search engine data processing system configured for authorship accountability in a blog search engine. The system can include a host server 230 with at least one processor and memory configured for communicative coupling to different client computing devices 210 over computer communications network 220. The host server 230 can support the execution of a blog search engine 240 within the memory of the host server 230. The blog search engine 240 can be configured to process search engine queries 260 for searching blog content in the Blogosphere.
In particular, the blog search engine 240 can produce a blog search UI 250 for distribution to the different client computing devices 210 with which end users can submit queries 260 to the blog search engine 240. On note, each of the queries 260 can specify not only query terms for conducting a query of blog content, but also one or more authorship criteria 280. Optionally, one or more of the queries 260 can further specify one or more content criteria 290. The authorship criteria 280 can include, by way of example, the degree to which an author of blog content is considered authoritative and the degree to which an author of blog content is considered trustworthy.
In the former instance, authoritativeness can be computed by determining a number of times a particular author has been published, a number of times others have commented on the blog content, or a number of others whom have subscribed to blog content authored by an author. As it is well known in the art, the computation of authoritativeness can be achieved by querying an application programming interface (API) to a publication source such as a blog or online database in order to determine a number of times content has been viewed, commented upon, linked to by other Web pages, or downloaded in the case of a published downloadable document. By comparison, trustworthiness can be computed by determining whether or not an author is known to the querying end user through inclusion in a list of contacts for the end user such as buddy lists social network friends or links lists, or frequent communications exchanged by the end user with the author.
Importantly, authorship sensitive relevance module 300 can be coupled to the blog search engine 240. The authorship sensitive relevance module 300 can include program code that when executed in the memory of the host server 230 is enabled to receive through the blog search UI 250 authorship criteria for query 260, and optionally content criteria. The program code further is enabled to compute a relevance for each blog content entry returned by the blog search engine 240 responsive to the query 260 based upon the authorship criteria, and optionally the content criteria. For instance, blog content entries returned by the blog search engine 240 in which a corresponding author is determined to be either or both authoritative and trustworthy can be ranked higher than other blog content entries returned by the blog search engine 240 for the query 260. Thereafter, the program code of the module 300 can return a sorted result set 270 providing a sort order of blog content from higher to lower relevance to a querying end user.
In even yet further illustration of the operation of the authorship sensitive relevance module 300, FIG. 3 is a flow chart illustrating a process for authorship accountability in a blog search engine. Beginning in block 305, a request can be received from an end user to compose a query to query blog content accessible over a computer communications network. In block 310, a search engine UI can be returned to the end user for completion with one or more query terms, authorship criteria, and optionally content criteria. In block 315, a completed form of the search engine UI can be received and in block 320, the authorship criteria can be extracted from the UI form, in block 325 one or more query terms can be extracted from the UI form, and in block 330 as an option content criteria can be extracted from the UI form.
In block 335, different weights for the different authorship and content criteria can be computed. By default, each different criteria can be weighted equally, however, in other aspects of the embodiment, the different criteria can be weighted disparately. In block 340, the query terms extracted from the UI form can be used in executing a query against blog content in the Blogosphere and in block 345, a set of search results can be returned responsive to the query, each of the search results referring to blog content. In block 350, the authorship criteria can be evaluated for each different author corresponding to each different entry in the result set. Likewise, where applicable, the content criteria can be evaluated for the blog content of each different entry in the result set. In block 355, a relevance value can be computed for each entry in the result set based upon the weighted combination of the evaluated criteria for each entry in the result set and in block 360 the entries of the result set can be sorted from entry of highest relevance to entry of lowest relevance. Finally, in block 365 the sorted result set can be returned to the querying end user.
