                Research Aim

• investigate different user search patterns and
  the adoption of different strategies to develop
  a typology of search patterns
• examination of keywords used at the
  beginning of the a search and developing a
  framework where they fit in

      Information search patterns of
                travellers
• General models to discover process and influencing
  factors (Fodness and Murray 1997, Vogt and
  Fesenmaier 1998, gursoy and Mc Cleary 2004)
• Multi-faceted factors in choice (Jeng and Fesenmaier
  2002)
• different orientation of travellers in their search
  (Grabler and Zins, 2004)
   – 6 decision styles (price, destination, accommodation,
     activities, highly-predefined, recommendation oriented)

    Information search on the web

• open text queries
  search is conducted by the user in his own words
• categorical search
  uses predefined categories which are developed by
    experts or on the base of user data
• combination search
  using keyword search within categories; mainly used
    within specialised search engines/search services


                   ENTER 2005 Research Track          5
       Simplicity in keyword search

• users submit only few queries per search, most of
  them only one
• these are very short
• additional features as relevance feedback or Boolean
  operators are rarely used, very often they are
  unnecessary and user apply them wrongly
• skewed keyword distribution
  few terms are repeatedly used and a lot of terms only
  once
• searches in the morning are longer, more queries are
  submitted
                                    Jansen et al 2000, Ozmutlu et al 2003b

     Trend of multitasking searches

• user submit several queries to subsequent
  topics which are suggested to be related to
  each other
• automatic topic identification helps to
  discover switching of topics (but methods
  need still improvement)


       He et al 2000, Ozmutlu et al 2003a, Ozmutlu and Cavadur 2004

Search strategies - external influences

• user goal and search purpose is a major
  factor
• influenced by interactive intentions
  identifying, learning, finding, locating, record,
    keeping, accessing, evaluating and obtaining)
• influenced by knowledge
  specific, common, area/location, general

                       Methodologies

• basis data set: internal log file of the search engine

    –   IP adress
    –   language
    –   city code
    –   keywords
    –   kind of task executed
    –   count of links

         Summary and conclusions

• general strong orientation on the city - users look for a
  particular city, browse or are getting inspirations for
  choosing a city
• keyword search highly used in combination with a
  particular city
• accommodation and destinations (places) are the
  categories user are searching for most
• keyword search is dominated by few keywords and
  few categories (accommodation, destination and
  information)  skewed distribution
• The homepage is not only the starting but also a re-
  starting point within the search process

                Limitations

• Specific example with specific result
• Ongoing changes, implementation and further
  development within the search engine might
  change results partly
• Time limitations
• User limitations




                ENTER 2005 Research Track   21
     Potential future developments

• Innovative space within inspirational path
• Further developments in the combination
  search of keywords within categories
• Using the knowledge of skewed distribution of
  keywords in improving search engine
  technologies
• Implementing the knowledge about the
  homepage as a re-starting point in its design
