Title: LIS454:Class 7


1
LIS-454Class 7
  • Factiva and the perils of business searching. The
    discussion around Federated Searching.

2
I Some aside notes
  • Advancing Science by making it accessible online
  • Geospatial data and security

3
II The perils of business searching
  • What are we looking at?
  • FIND.COM
  • How is business searching different from other
    areas of searching?
  • Where is the data usually located?

4
Information quality
  • Business research is about high quality
    information
  • Business research is about identifying
    information needs

5
Private vs. Public
  • Private companies do not have to disclose
    financial information.
  • America's Largest Private Companies - Forbes.com
  • Sarbanes-Oxley Act - Wikipedia, the free
    encyclopedia

6
Searching for government information?
  • Business.gov
  • International Trade Commission Homepage
  • http//cbdnet.gpo.gov/cbdhints.pdf

7
Numbers and codes
  • Sales figures
  • Market share
  • Demographic indicators
  • Charts
  • Graphs

8
Industrial codes
  • NAICS -- North American Industry Classification
    System
  • Fascinating use of controlled vocabulary?
  • Used by USA, Mexico, and Canada.
  • Verify that you are using the appropriate NAIC
    code (1997 or 2002).

9
Industrial codes
  • Kompass UK - Connects Business to Business
  • IT Wales - Other nation's Business Directories
  • Factiva contains also codes, but the advantage is
    that you can look at them alphabetically.

10
Industrial Codes
  • Dialog offers you the option of searching for
    primary (PC) or secondary industry (SC).
  • Companies with multiple lines of business are a
    problem.
  • Investing News, Personal Finance, Stock Market,
    Mutual Funds, Investments More Reuters.com

11
Reliability and accuracy
  • Report numbers in business are usually
    unambiguous.
  • Keep your eyes opened though

12
The logical sources
  •  The obvious source of corporate numbers is the
    company itself, which issues press releases and
    frequently posts its financials on the corporate
    Web site. Other sources include SEC filings,
    available through many fee-based services as well
    as the SEC itself, and secondary sources such as
    Hoover's, Standard Poor's, ValueLine, and
    Mergent.

13
In the international arena
  • Numbers and stats are sometimes difficult to
    find.
  • Some nations may not be very interested in
    sharing data.
  • Lack of updated stats
  • UN/FAO/IMF/World Bank/OECD

14
III Federated Search In the Star Trek world
  • What would be the ideal information retrieval
    system? Would it be similar to Star Trek, where
    the patron simply asks the computer a question
    and in a matter of moments receives the
    applicable information in the format needed? We
    have not arrived at this utopian version of
    research libraries, but we are closer than we
    were a few years ago. Technological advances have
    changed the way research is done. Online
    databases enable faster, more precise searching
    than their print counterparts. Many electronic
    databases provide patrons with access to full
    text of the articles from their homes or offices.

15
One finger, multiple searches.
  • More Appealing
  • Time saving
  • Using one only interface is less intimidating for
    the user (Baer, 2004)

16
LIS-454
  • In the academic world students can be deeply
    confused by the need to search multiple
    interfaces. 
  • Federated search seems to be the solution to this
    confusion.

17
Print and electronic
  • Federated search can be useful also for printed
    and electronic collections.

18
The usefulness of Federated searching
  • A single search interface seems to be the ideal
  • Individual dbases have their unique features
    (commands, syntax, etc.)
  • The power of an individual dbase search might be
    sacrificed
  • For some people is a step backwards
  • The Google style gets privileged

19
Just a couple of keywords
  • Records that are not full text may be at a
    disadvantage
  • The less terms the better (Curtis Dorner/KQ)

20
Some additional issues
  • Implementation of FS is complex
  • Sometimes slow response time
  • First display results might be a choice
  • Good enough results are privileged
  • Some high quality results may be missed
  • Simplicity is the goal. (Fahey, 2007)

21
Different names
  • The use of multiple names to describe the same
    thing plagues the information industry. Federated
    search is no exception. NISO, the U.S. National
    Information Standards Organization, and many
    libraries claim federated searching as
    metasearching. However, vendors in this space
    prefer not to be known as metasearch engines, as
    this conjures up thoughts of searching only
    previously crawled databases such as Google,
    AlltheWeb, and AltaVista. (Fryer, 2004)

22
Marketing names
  • Difference between federated searching and
    metasearching
  • FS are enterprise software
  • FS concentrates on textual information ignored
    usually by web sources.
  • Free search is mostly associated with web
    oriented metasearch engines

25
Metasearch and the Google factor
  • Google has radically changed users' expectations
    and redefined the experience of those seeking
    information. For many searchers, the quality of
    the results matter less than the processthey
    just expect the process to be quick and easy.
    (Luther, Library Journal, 2003)

26
Metasearch
  • One of the major advantages of metasearch is that
    results can be obtained from multiple databases
    without having to repeat a search. Large public
    and academic libraries typically subscribe to
    between 100 and 400 databases. Given the
    multidisciplinary nature of research, users
    looking for "the" answer will find that
    metasearching facilitates discovery of databases
    that they otherwise may not have consulted. The
    novice user looking for "an" answer can find
    results in multiple sources with a single search.

27
Presentation of results
  • Merged results
  • Separated results
  • Matter of debate among users and hosts
  • User preferences may affect the purchasing
    decision

28
Some examples
  • ARL Scholars Portal
  • MuseGlobal
  • At its heart, metasearch is about providing easy
    access for the user to complex resources. It is
    not a tool that allows librariansor other expert
    users to search with greater precision. It's not
    for us, it's for the average user.

29
Some potential problems
  • It is easy when using a metasearch tool,
    especially if you are a novice user, to choose to
    search all files. After all, more can only be
    better, right? This has caused concern among
    publishers, aggregators, and other content
    providers that their systems can't handle the
    greatly increased usage that occurs when every
    search is run against every database. The
    likelihood of system overload grows with each
    library that adds a metasearch tool, impacting
    system resources and performance. This can be
    particularly problematic for smaller, specialized
    databases that were never designed to support
    such high traffic.

30
Some potential problems 2
  • A federated search engine will pass on the search
    to each database, but the individual databases
    interpret the search terms differently. Some
    databases support Boolean logic while some do
    not. Are two search terms entered next to each
    other interpreted as a phrase, or will and or
    logic be used? Is the search limited to the
    title, abstract, descriptors, or full-text of the
    article? Each database interprets the search as
    it normally would, but the differences aren't
    apparent.

31
Some potential problems 3
  • Implications for scholarly research but students
    in academic environments
  • One-stop searching mentality makes teaching good
    information-seeking habits harder.
  • Challenge for Library instruction

32
Some potential problems 4
  • Lack of relevance ranking
  • What does relevance bring to the search?
  • Tension between the seasoned and the average
    searcher.

33
Metasearch nothing new
  • Metasearch isn't a new concept. Dialog in the
    1970s and subsequently SilverPlatter executed a
    single search simultaneously across multiple
    bibliographic databases. In the web era,
    meta-search engines such as Meta-crawler merge,
    dedupe, and rank the results of multiple web
    search engines such as Ask Jeeves, FAST (which is
    used by LexisNexis), and Overture (which is being
    acquired by Yahoo).

IV Some Factiva tips
  • Advice Look at the manual

35
Searching for Brazil
  • Factiva Intelligent Indexing

Brazil and political and general news
37
Searching for Brazil
38
The Codes 1
  • Factiva Intelligent IndexingTM Key Facts
  • These terms are based on indexing standards
    including NAICS (for Industry), ISO (for Regions)
    and IPTC (for News). There are up to five levels
    of hierarchy within Factiva Intelligent
    IndexingTM this means that when selecting the
    industry term for Telecommunications, you will
    also be searching all of the granular
    telecommunications terms. Terms are reviewed
    quarterly for new additions customers receive a
    45-day notice before new terms are used. More
    information about Factiva Intelligent IndexingTM
    is available at www.factiva.com/indexing

39
The Codes 2
  • Using codes in your search
  • There may be times when you choose to use the
    indexing codes in your search rather than the
    terms. To do this click on the next to the
    Factiva Intelligent Indexing term and it will
    automatically be dropped into the Free text box.
    For example, company codes are preceded with fds
    (fds means Factiva Data Symbol). When selecting
    an industry, region or subject term you will see
    the actual code for those terms, such as iniint
    for Internet and Online Services. Codes are
    placed in the Free text box without connectors.
    You must manually place connectors between the
    codes.

40
Look Up feature 1
41
Look Up feature 2
  • Reverse Code Look up
  • You can also locate Factiva Intelligent Indexing
    terms by entering the corresponding code in the
    Look up box. If you enter the code c181 in the
    Look up box and hit enter, you will get back the
    equivalent Factiva Intelligent Indexing term for
    Acquisitions/Mergers/Takeovers.
  • This feature is particularly useful for users who
    have created complex searches using Factiva
    Intelligent Indexing codes. These search
    strategies often include indexing codes that may
    be difficult to identify upon revision. For
    example, a search strategy may look like the
    followingfdsmcrost and nsc181 and ini330202.
