Ideally, such endeavors will mean the reassessment of the initial exclusion criteria for knowledgebase materials. The increasing number of books published and republished in electronic format, for example, means that the inclusion of monograph-length studies of the Sonnets is no longer a task so onerous as to be prohibitive. Indeed, large-scale digitization projects such as Google Books and the Internet Archive are also making a growing number of books, both old and new, available in digital form.

4.5. experiment: the rekn crawler

We recognized that the next stages of our work would be predicated on the ability to create topic- or domain-specific knowledgebases from electronic materials. The work, then, pointed to the need for a better Internet resource discovery system, one that allowed topic-specific harvesting of Internet-based data, returning results pertinent to targeted knowledge domains, and that integrated with existing collections of materials (such as REKn) operating in existing reading systems (such as PReE), in order to take advantage of the functionality of existing tools in relation to the results. To investigate this further, we collaborated with Iter, a not-for-profit partnership created to develop and support electronic resources to assist scholars studying European culture from 400 to 1700 CE. On the mandate, history, and development of Iter, see Bowen (2000, 2008). For a more detailed report on this collaborative experiment, see Siemens, et al. (2006).

4.5.1. premises

We thought we could use technologies like Nutch and models from other more complex harvesters (such as DataFountains and the Nalanda iVia Focused Crawler) See also Mitchell (2006). to create something that would suit our purposes and be freely distributable and transportable among our several partners and their work. In using such technologies, we hoped also to explore how best to exploit representations of ontological structures found in bibliographic databases to ensure that the material returned via Internet searches was reliably on-topic.

4.5.2. method

The underlying method for the prototype REKn Crawler is quite straightforward. An Iter search returns bibliographic (MARC) records, which in turn provide the metadata (such as author, title, subject) to seed a web search, the results of which are returned to the knowledgebase. In the end, the original corpus is complemented by a collection of pages from the web that are related to the same subject. While all of these web materials may not always be directly relevant, they may still be useful.

The method ensures accuracy, scalability, and utility. Accuracy is ensured insofar as the results are disambiguated by comparison against Iter’s bibliographic records—that is, via a process of domain-specific ontological structures. Scalability is ensured in that individual searches can be automatically sequenced, drawing bibliographic records from Iter one at a time to ensure that the harvester covers all parts of an identified knowledge domain. Utility is ensured because the resultant materials are drawn into the reading system and bibliographic records are created (via the original records, or using Lemon8-XML).

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
