Sort Hits for Relevance?
TOPIC: Dialog is much more than a search engine. It empowers you to slice and dice the data in many ways to pull information together quickly. One specialized feature is the new SORT HITS command: SORT S#/ALL/HITS. SORTing by “hits” on your search terms lets you target relevancy. The command is best used in fulltext databases, such as NewsRX Weekly Reports (File 135), in the biotechnology/bioscience arena. What’s more, you can incorporate this command into Alerts.
Related databases include Adis Newsletters (File 428,429), Prous Science Daily Essentials (File 458, 459), Pharmaceutical and Healthcare Industry News Database (PHIND) (File 129*,130*) and Dialog NewsRoom (File 990).
*(Subscriber access.)
In this example, you will run a search in NewsRX Weekly Reports on adult stem cells. Then you will use the Sort command to rearrange the results by relevancy.
COMMAND SUMMARY
BEGIN 135
SELECT ADULT(3N)STEM(W)CELL?
SELECT S1/2005:2008
REMOVE DUPLICATES
SORT S3/ALL/HITS
TYPE S4/8,K/1-2
Click Links > Display > Type Full Record
HOW TO...
1. BEGIN File 135, NewsRX Weekly Reports, to get updates on biotechnological developments.
2. SELECT terms. Be sure to use proximity connectors when searching a phrase. (N) specifies that terms are next to each other in either order. A number in front of N denotes within so many words. (W) or () stipulates that terms appear next to each other in exact order. A question mark after a word allows for variant word endings.
3. Use a database LIMIT feature to restrict retrieval to a range of years. The colon acts as OR. |
 |
4. REMOVE DUPLICATES (RD). It is possible to remove duplicates even in just one database. RD creates a new search set.
5. SORT all the records in the RD set (S3) by “hits” of the search terms. This creates a new search set (S4) sorted by relevancy in descending order. The record with the highest incidence becomes the first record. |
 |
6. TYPE a few records in Formats 8 and K (KWIC) to see titles, indexing, publication dates, word counts and Key Words in Context.
Notice the amount of “hits” in the first records.
7. Click Links at the top of the record you want to see in more detail > Display > Type Full Record.
Note: Only portions of the first record appear. |
 |
The fulltext of record 1 displays.
Note: A portion of the record is omitted from this display. |

Biotech company developing treatments based on adult
stem cells
Biotech Business Week, July 18, 2005, p.399
DOCUMENT TYPE: Expanded Reporting LANGUAGE: English
RECORD TYPE: FULLTEXT
AUDIENCE: Consumer
Word Count: 1026
TEXT: As Congress spent hours passionately debating the
merits and ethics of embryonic stem cell research, nearly 50
Osiris Therapeutics, Inc., employees of the company continued
their work on less controversial adult stem cells.
Thanks to U.S. Food and Drug Administration (FDA)fast-
track designation, Osiris expects to have an adult stem cell-
based therapy on the market by late 2007 to combat potentially
fatal tissue rejection among leukemia patients undergoing bone
marrow transplants. That's one of three adult stem cell-based
therapies Osiris currently has in human trials, to the delight
of investors who muscled their way into the company's latest
funding round to raise $50 million, more than double the
expected amount.
Another human clinical trial squirts adult stem cells
into damaged knees after surgery to regrow meniscus, restoring
the tissue that acts as a shock absorber and preventing onset
of arthritis. The third experimental therapy being tested in
humans - including patients here at the Johns Hopkins University
School of Medicine - uses adult stem cells to help replace tissue
damaged by heart attacks.
