Perhaps you should try some spelling variations:
"sentiment based algorithms" » "sentiment based algorithm" (Expand Search), "sentiment dataset algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("sentiment based algorithms") OR ((("element method algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sentiment based algorithms\") OR (((\"element method algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( sentiment based algorithms ) OR ((( element method algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("sentiment based algorithms") OR ((("element method algorithm") OR ("neural coding algorithm"))))*.
