Most summarization task focuses on generating relatively short summaries. Such a length constraint might not be appropriate when summarizing scientific work. The LongSumm task needs participants generate long summary for scientific document. This tas
k usual can be solved by language model. But an important problem is that model like BERT is limit to memory, and can not deal with a long input like a document. Also generate a long output is hard. In this paper, we propose a session based automatic summarization model(SBAS) which using a session and ensemble mechanism to generate long summary. And our model achieves the best performance in the LongSumm task.
GPS technology considers the essential tool for establishing geodetic networks.
Static method of GPS is used often in observing geodetic network points. Establishing
geodetic networks using GPS requires accuracy, consistency and economency.
This p
aper discusses influence of observation mode and number of GPS receivers in
accuracy of calculating of coordinates of points. Coordinates of network points are
clculated using tow and three GPS receivers and with diferent methods like radial, traverse,
network.
Comparison between coordinates for network points obtained by several cases is
performed. The differences between coordinates indicate accuracy of network method in
calculating coordinates when three or more receivers are avlible. When tow receivers are
avilable the radial method is the best in accuracy and consistency.
