1. Posting skip pointers. for a postings list of length P, use √P evenly-spaced skip pointers. This heuristic can be improved upon; it ignores any details of the distribution of query terms.

2. Most recent search engines support a double quotes syntax (“stanford university”) for phrase queries, which has proven to be very easily understood and successfully used by users.

 
3. The concept of a biword index can be extended to longer sequences of words, and if the index includes variable length word sequences, it is gen- erally referred to as a phrase index.

 
4.For the reasons given, a biword index is not the standard solution. Rather, a positional index is most commonly employed.

 
5.Let’s examine the space implications of having a positional index. A post- ing now needs an entry for each occurrence of a term. The index size thus depends on the average document size. The average web page has less than 1000 terms, but documents like SEC stock filings, books, and even some epic poems easily reach 100,000 terms. Consider a term with frequency 1 in 1000 terms on average. The result is that large documents cause an increase of two orders of magnitude in the space required to store the postings list:

Expected Expected entries Document size postings in positional posting
1000 1 1 100,000 1 100 

How to give more persuasive presentations: A Q&A with Nancy Duarte

The speaker needs the audience more than the audience needs the speaker.

 Going from sounding memorized and canned to sounding natural is a lot of work.

 What is the best way to start creating a presentation?

My best advice is to not start in PowerPoint.

But on the stage, you have to move your body in really big gestures.

Keynote address: Library and information science as a research domain: problems and prospects

Most recently, LIS schools were accused by leaders of the profession of failing to educate students appropriately for the workplace and of engaging in esoteric and irrelevant research that was out of touch with real world needs.

While, A community of information schools known as the "iSchool Caucus" has been founded that has no affiliation with a professional association in LIS yet it contains significant numbers of the leading LIS programs in North America.  

LIS:two camps: the library and the information sides.

we might all agree generally that issues of information retrieval, information quality and authenticity, policy for access and preservation, the health and security applications of data mining, raise at least some big questions for information research to study.

  

The points made about IR can be made more or less equivalently, I'd argue, for many other of the current hot topics in information research. We are at the party, so to speak, but we are rarely the center of attention.  

What are the big questions?

It is important to remember that the value of LIS make it a potentially strong contributor to the debate and analysis of such issues.
