This User's Guide page introduces and instructs basic how to do's of the system, and also how the system works.

Required Platform and Web Browser
Físchlár-News Stories has been configured for:
  • Microsoft Windows-based PCs (Windows 95, NT, 98, 2000, XP)
  • Microsoft Internet Explorer v5+
  • Screen resolution at least 1024 x 768
Other specifications might work but have not been thoroughly tested. Also lower screen resolution can be used but excessive scroll bars will appear, reducing the usability of some features of the interface. The system uses Cascading Stylesheet (CSS), JavaScript, Java Applets - so these features should be enabled on your web browser setting if you use your own PC.

A small software plug-in (Oracle Video Player) needs to be installed for video playback - see 'Installing Video Player Plug-in' section below.

Registration & Logging-in
Every user of the system first has to register. When you visit Físchlár-News Stories site (http://www.fischlar.dcu.ie/news/), the page will ask you to either register (first time only) or log in (once registered) as the screen shot on the right shows. For registration, click the "Register..." button, and on the following page type in your full email address then click "Register" button. After a few seconds, you will have received an email from the system, confirming your registration with a password - so check your email and note the password in this email. Once you have this, you can log in to the system by typing in your full email address and password on the Login page. Once you are logged in, you can change your password into something more memorable - by clicking on "My Account" button on the bottom right.

Installing Video Player Plug-in
If you want to access on your own PC, you require the installation of a small piece of software that will play the video over the network… a task that takes about 2 minutes. If you have not used any variation of the Físchlár system before from your PC, this means you will have to download the Oracle Video Player plug-in to play the video (the plug-in is downloadable from http://www.fischlar.dcu.ie/video/plugin/ … download the file and say YES or OK to all of the questions the installation process asks). If you require some help doing this then contact fischlar@computing.dcu.ie and we would be glad to help.

The installation will finish with the message saying "the installation is complete". Usually you don't need to restart the computer. Now you can play videos available on Físchlár.

Browsing and Playing the News Stories
Once you are logged in, you will see on the left side of the screen the monthly calendar with the current month at the top (see Figure beside). The days in yellow are the days for which the evening news are available for story searching, browsing and playback. Notice the archive starts from 23 April 2003 (bottom of the calendar), to the yesterday (top of the calendar).
Clicking on any of the days will show the list of that day's news stories on the right side of the screen (see Figure beside). Each story is summarise with a single image (showing the anchorperson starting that story), first few lines of the anchorperson's announcement, link to more detailed browsing and playback option. To play a story, click on "Play this story" link at the end of the story summary - a player window will pop up and start streamed playback from that story onwards. To view it in full-screen, right-mouse click inside the player and select "Full-screen" (or a simple short-cut by Alt-Enter).

Rating of Stories
Notice the thumbs-up and -down icons beside each story: this is 5-scale rating icons with which you should indicate your level of preference on that story. Whenever you see these thumbs icons, please click on one of the 5 icons, to let us know how much you like (or dislike) this particular news story. We will be able to personalise the system by getting your preference indications during your registered period, so that we can recommend a few stories that will be of interest to you in the future. Once you indicated your preference for a story, the icon colour will change reflecting your preference. From now on, whenever you come across this particular story again, you will see that your indication has been remembered and displayed.

Browsing More Detail
On the story list (news summary), clicking on the anchorperson image of a story will bring you to the shot-level browsing screen. In this view, all camera shots in that story (reporter, interview, etc.) are browsable along with full closed caption text. Clicking on any of the images will start streamed playback from the clicked point onwards. This allows you not to have to play a whole story if you want to see only a specific part in the story. You will notice thumbs-up and -down icons on this screen, too, so in case you haven't indicated your preference on this story yet, please do so.

Jumping among the Related Stories
Below the story detail, you will see "Related Stories" - the list of other news stories in the archive that were considered related to the currently browsed story. Jump to that story's detail, or jump to the news story list on the day in which a story came from, or you can simply play that story. When you jump to another story, you will see it has its own list of Related Stories at the end... in this way, you can browse from a story to another to another.

Searching the News Stories
You can search news stories by typing in word(s) in the text box on the screen, similar to as you do with a search engine on the web. The search result will be displayed on the right side of the screen, showing the list of news stories in the archive that matched your query term(s). Searching is done on the whole collection (from 25 April 2003 to yesterday), not on a particular date displayed on the screen. For a query with multiple terms, see the examples below:
  • palestinian israeli ( = palestinian OR israeli)
  • michael AND jackson
  • mars NOT nasa
The search result list is same format as the story list of a day - link to more detail or playback the stories - but the stories in the search results are collected throughout different days' news.

Automatic Recommendation of News Stories
If you don't have time to browse throught the archive, just click on the 'Recommended button as seen in figure beside. This will show you a few personalised news stories selected across the archive that you will likely to want to see, including recently appeared stories - this is the result of your thumbs rating (see 'Rating of Stories' above) from which the system has figured out what stories you haven't seen that would be of interest to you. The recommended story list will be different for individual users, and at different time of access. Browse and play the recommended stories as any other stories.

Forgot Your Password?
If you forgot the password and unable to log in, don't worry - simply click on "Forgot Password?" button on the first page. Físchlár system will email you with the password in seconds. It is a good idea to change the password into something more memorable, by clicking on "My Account" button on bottom right corner (you need to log in first to be able to change your password).

How Does the System Work?
The diagram below illustrates at a glance how the system works. When the evening news is broadcast on TV, it is encoded by the system into MPEG-1 file (standard video format), then goes through a series of automatic content analysis techniques, including Shot Boundary Detection, keyframe extraction, face detection, advertisement detection and news story segmentation. The result is news story-based searching/browsing features of the system.
